Technical Field

[0001] The invention relates to the technical field of automated welding equipment, in particular to an automated welding device for a cylindrical main furnace chamber of a single crystal furnace. Background Art

[0002] Since the temperature during silicon single crystal production is relatively high, in order to prevent the volatilization of the material of the main furnace chamber shell from affecting the purity of the silicon single crystal, and considering that the main furnace chamber shell also needs to have excellent corrosion resistance, plasticity, weldability, paramagnetism and other properties, austenitic stainless steel is currently generally used as the material in combination with argon arc welding to prepare the main furnace chamber shell.

[0003] Among them, the main furnace chamber is cylindrical. If linear welding is used, after welding is completed, the welding position will be affected by the arc surface of the cylinder, which will cause unstable welding or small gaps, affecting the welding effect. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an automatic welding device for a cylindrical main furnace chamber of a single crystal furnace, comprising a base, a limit ring is fixedly connected to the top of the base, a motor is fixedly connected to the top of the base, a threaded rod is fixedly connected to the output shaft of the motor, and a gear rod is fixedly connected to the top of the base;

[0005] The linkage mechanism includes a threaded block meshingly connected to the outer wall of the threaded rod, a mounting block fixedly connected to the side wall of the threaded block, a limit plate fixedly connected to the outer wall of the mounting block, a gear rotatably connected to the side wall of the mounting block, a sector gear 1 fixedly connected to the side wall of the gear, and an adjustment component fixedly connected to the side wall of the mounting block;

[0006] The driving mechanism comprises a fixed bracket fixedly connected to the side wall of the mounting block, a rotating rod rotatably connected to the inner wall of the fixed bracket, a second sector gear fixedly connected to the side wall of the rotating rod, a rotating long rod rotatably connected to the side wall of the mounting block, an end of the rotating long rod away from the mounting block is fixedly connected to the support frame, a prying rod 1 is rotatably connected to the inner wall of the support frame, and a feeding assembly is fixedly connected to the side wall of the mounting block;

[0007] The welding mechanism includes a fixing frame fixedly connected to the outer wall of the rotating long rod, a sliding round rod is slidably connected to the inner wall of the through hole of the fixing frame, a fixing ring is fixedly connected to the outer wall of the sliding round rod, a pulling spring is fixedly connected to the outer wall of the fixing ring, and a welding machine is fixedly connected to the outer wall of the sliding round rod. In view of the problem that welding deviation is prone to occur in cylinder welding, a prying rod and a fixing frame are arranged inside the equipment. When using the equipment, the raw material to be welded is placed on the top of the base, and the accurate position is determined by the limit ring to ensure that the limit plate is deeply inserted into the welding groove, and the power of the motor is turned on. At this time, the threaded rod rotates to drive the threaded block to move up and down, and the threaded block drives the gear through the mounting block The wheels move up synchronously, and the gear rotates under the influence of the toothed rod during the upward movement. The rotation of the gear drives the rotating rod to rotate through the fan-shaped gear 2, and the fixed bracket drives the prying rod 1 to rotate. The circular rotation of the prying rod 1 forms a regular left and right rotation through the restriction of the support frame. The support frame drives the fixed frame and the sliding round rod to swing left and right regularly by rotating the long rod. The sliding round rod drives the welding machine to move up and down on the surface of the cylindrical raw material, forcing the welding machine to swing to the left and right ends to increase the welding area. Through the application of the above components, the welding machine presents a "Z"-shaped motion pattern during operation, thereby ensuring the welding strength of the weld of the cylindrical main furnace chamber of the single crystal furnace.

[0008] Preferably, the adjustment assembly includes a rotating square plate rotatably connected to the side wall of the mounting block, a vortex spring is fixedly connected to the inner wall of the through hole of the rotating square plate, a rubber track is fixedly connected to the side wall of the linkage mechanism, and one end of the vortex spring away from the rotating square plate is fixedly connected to the outer wall of the mounting block.

[0009] Preferably, the adjustment component also includes an L-shaped rod fixedly connected to the side wall of the rubber track, one end of the L-shaped rod away from the rubber track is rotatably connected to the top of the rotating square plate, and one end of the pulling spring away from the fixing ring is fixedly connected to the bottom of the fixing frame. Utilizing the regular swinging characteristics of the above fixing frame, a rubber track is arranged inside the equipment, wherein, when the equipment is running, the rotating square plate is affected by the mechanical power released by the vortex spring, and the vortex spring will drive the rotating square plate to rotate downward, forcing the outer wall of the ball bearing to be in a close contact state with the outer wall of the cylindrical main furnace chamber, and the rotating square plate forces the two ends of the rubber track to bend downward through the L-shaped rod, so that the downward bending angle of the rubber track is the same as that of the outer wall of the cylindrical main furnace chamber. The curvatures of the outer walls of the cylindrical main furnace chamber are equal. When the fixed frame swings, the fixed frame drives the sliding round rod to move along the deformed inner wall of the rubber track. At this time, the top of the fixed ring and the top of the rubber track are in a sliding state. When the fixed ring slides to the lower position on both sides of the rubber track, the pulling spring will drive the fixed ring, the sliding round rod and the welding machine to move downward synchronously. When the fixed ring slides to the highest point in the center of the rubber track, the fixed ring will drive the welding machine to move upward synchronously. Through the application of the above components, the distance between the welding machine and the outer wall of the cylindrical main furnace chamber can be effectively controlled to ensure that the welding distance will not be affected by the outer wall of the cylinder, thereby improving the welding efficiency of the equipment.

[0010] Preferably, the adjustment assembly also includes a ball bearing rotatably connected to the bottom of the rotating square plate, one end of the prying rod 1 close to the fixed bracket is rotatably connected to the outer wall of the rotating rod, and the outer wall of the sector gear 2 is meshingly connected to the outer wall of the sector gear 1.

[0011] Preferably, the feeding assembly includes a fixed square plate fixedly connected to the side wall of the mounting block, a hydraulic telescopic rod is fixedly connected to the side wall of the fixed square plate, and one end of the hydraulic telescopic rod away from the fixed square plate is fixedly connected to the side wall of the welding machine.

[0012] Preferably, the feeding assembly also includes a hydraulic telescopic rod 2 fixedly connected to the side wall of the fixed square plate, one end of the hydraulic telescopic rod 2 away from the fixed square plate is fixedly connected to the extrusion groove, and a pressure rod is fixedly connected to the side wall of the extrusion groove.

[0013] Preferably, the feeding assembly also includes a pulling spring rod fixedly connected to the side wall of the fixed square plate, one end of the pulling spring rod away from the fixed square plate is fixedly connected to a pulling rod, and one end of the pulling rod away from the pulling spring rod is rotatably connected to a prying rod 2, and the outer wall of the gear is meshed and connected with the outer wall of the gear rod. The hydraulic telescopic rod 1 is compressed to drive the welding rod to feed independently. When the welding machine squeezes the hydraulic telescopic rod 1 to feed, the welding machine will contact one end of the fed welding rod, and the high-temperature welding machine will melt the welding rod, so that the molten welding rod sticks to the cylindrical main furnace chamber. The welding machine swings to the other end, and the solution inside the hydraulic telescopic rod 2 returns to the inside of the hydraulic telescopic rod 1 to reset each component. However, the pulling spring rod has been in an extended state during the previous feeding. When the extrusion groove begins to reset, the extrusion groove is still in a tight state. The clamping force of the extrusion block on the welding strip still exists, and while the extrusion groove is reset, the welding strip is driven away from the molten metal melt. Through the application of the above components, the molten melt is prevented from contacting and cooling with the unmelted welding strip, which affects the normal discharge of the subsequent welding strip.

[0014] Preferably, the feeding assembly also includes an extrusion block fixedly connected to the end of the prying rod 2 away from the pull rod, the side wall of the prying rod 2 is rotatably connected to the inner wall of the extrusion groove, and a welding strip is slidably connected to the inner wall of the through hole of the fixed square plate. Utilizing the swinging characteristics of the above-mentioned welding machine, a hydraulic telescopic rod 1 is arranged inside the equipment. When the welding machine swings left and right, the hydraulic telescopic rod 1 at one end is squeezed, and the internal space of the hydraulic telescopic rod 1 is reduced, so that the internal solution of the hydraulic telescopic rod 1 enters the interior of the hydraulic telescopic rod 2 through the fixed square plate, so that the hydraulic telescopic rod 2 generates an extension force, and the hydraulic telescopic rod 2 pushes the extrusion groove and the prying rod 2 to move. In this process, one end of the prying rod 2 is affected by the pulling spring rod and the pull rod, so that the other end of the prying rod 2 is tilted upward, forcing the extrusion block to contact the outer wall of the welding strip, and the other side of the welding strip is restricted by the pressure rod, so that the extrusion block and the pressure rod form a clamping force, and as the extrusion groove moves outward, the clamped welding strip is sent into the processing area. Through the application of the above-mentioned components, the autonomous feeding of the equipment is guaranteed.

[0015] The present invention has the following beneficial effects:

[0016] (1) In order to solve the problem that welding deviation is prone to occur during cylinder welding, the present invention provides a prying rod 1 and a fixed frame inside the equipment. When the equipment is used, the raw material to be welded is placed on the top of the base, and the accurate position is determined by the limit ring to ensure that the limit plate is deeply inside the welding groove, and the power of the motor is turned on. At this time, the threaded rod rotates, driving the threaded block to move up and down. The threaded block drives the gear to move up synchronously through the mounting block. During the upward movement, the gear is affected by the toothed rod to rotate. The rotation of the gear drives the rotating rod to rotate through the fan gear 2. The fixed bracket drives the prying rod 1 to rotate. The circular rotation of the prying rod 1 forms a regular left and right rotation through the restriction of the support frame. The support frame drives the fixed frame and the sliding round rod to swing left and right regularly through the rotating long rod. While the sliding round rod drives the welding machine to move up and down on the surface of the cylindrical raw material, it forces the welding machine to swing to the left and right ends to increase the welding area. Through the application of the above components, the welding machine presents a "Z"-shaped movement law during operation, thereby ensuring the welding strength of the weld of the cylindrical main furnace chamber of the single crystal furnace.

[0017] (2) The present invention utilizes the characteristic of the regular swing of the above-mentioned fixed frame, and a rubber track is arranged inside the equipment. When the equipment is running, the rotating square plate is affected by the mechanical power released by the vortex spring, and the vortex spring will drive the rotating square plate to rotate downward, forcing the outer wall of the ball bearing to be in a close contact state with the outer wall of the cylindrical main furnace chamber, and the rotating square plate forces the two ends of the rubber track to bend downward through the L-shaped rod, so that the downward bending angle of the rubber track is equal to the curvature of the outer wall of the cylindrical main furnace chamber. When the fixed frame swings, the fixed frame drives the sliding round rod to move along the deformed inner wall of the rubber track. At this time, the top of the fixed ring and the top of the rubber track are in a sliding state. When the fixed ring slides to the lower position on both sides of the rubber track, the pulling spring will drive the fixed ring, the sliding round rod and the welding machine to move downward synchronously. When the fixed ring slides to the highest point in the center of the rubber track, the fixed ring will drive the welding machine to move upward synchronously. Through the application of the above-mentioned components, the distance between the welding machine and the outer wall of the cylindrical main furnace chamber is effectively controlled to ensure that the welding distance will not be affected by the outer wall of the cylinder, thereby improving the welding efficiency of the equipment.

[0018] (3) The present invention utilizes the swinging characteristics of the welding machine and is provided with a hydraulic telescopic rod 1 inside the equipment. When the welding machine swings left and right, the hydraulic telescopic rod 1 at one end is squeezed, and the internal space of the hydraulic telescopic rod 1 is reduced, so that the solution inside the hydraulic telescopic rod 1 enters the hydraulic telescopic rod 2 through the fixed square plate, so that the hydraulic telescopic rod 2 generates an extension force, and the hydraulic telescopic rod 2 pushes the extrusion groove and the prying rod 2 to move. During this process, one end of the prying rod 2 is affected by the pulling spring rod and the pulling rod, so that the other end of the prying rod 2 is tilted upward, forcing the extrusion block to contact the outer wall of the welding strip, and the other side of the welding strip is restricted by the pressure rod, so that the extrusion block and the pressure rod form a clamping force, and as the extrusion groove moves outward, the clamped welding strip is sent into the processing area. Through the application of the above components, the autonomous feeding of the equipment is guaranteed.

[0019] (4) The present invention utilizes the characteristic that the hydraulic telescopic rod 1 is compressed to drive the welding rod to feed independently. When the welding machine squeezes the hydraulic telescopic rod 1 to feed, the welding machine will contact one end of the fed welding rod. The high-temperature welding machine will melt the welding rod, causing the molten welding rod to stick to the gap inside the cylindrical main furnace chamber to complete a single welding. At this time, the welding machine swings to the other end, and the solution inside the hydraulic telescopic rod 2 will return to the inside of the hydraulic telescopic rod 1 to reset each component. However, the pulling spring rod has been in an extended state during the previous feeding. When the extrusion groove begins to reset, the extrusion groove is still in a tight state. The clamping force of the extrusion block on the welding rod still exists, and when the extrusion groove resets, the welding rod is driven away from the molten metal melt. Through the application of the above components, it is avoided that the molten melt contacts and cools the unmelted welding rod, which affects the normal discharge of the subsequent welding rod.

In view of the problem that welding deviation is prone to occur in cylinder welding, a prying rod 36 and a fixing frame 41 are arranged inside the equipment. When using the equipment, the raw material to be welded is placed on the top of the base 1, and the accurate position is determined by the limit ring 12 to ensure that the limit plate 23 is deeply inserted into the welding groove, and the power supply of the motor 13 is turned on. At this time, the threaded rod 14 rotates, driving the threaded block 21 to move up and down, and the threaded block 21 passes through the mounting block 22 The gear 24 is driven to move upward synchronously. During the upward movement, the gear 24 is affected by the toothed rod 15 to rotate. The rotation of the gear 24 drives the rotating rod 32 to rotate through the fan gear 2 33. The fixed bracket 31 drives the prying rod 1 36 to rotate. The circular rotation of the prying rod 1 36 is restricted by the support frame 35 to form a regular left and right rotation. The support frame 35 drives the fixed frame 41 and the sliding round rod 42 to swing left and right regularly by rotating the long rod 34.

Through the application of the above-mentioned components, the welding machine 45 presents a "Z"-shaped motion pattern during operation, thereby ensuring the welding strength of the weld of the cylindrical main furnace chamber of the single crystal furnace.

[0036] For example 2, please refer to Figure 6 - Figure 8The present invention is an automated welding device for a cylindrical main furnace chamber of a single crystal furnace. Based on Example 1, the adjustment component 5 includes a rotating square plate 51 rotatably connected to the side wall of the mounting block 22, a vortex spring 52 is fixedly connected to the inner wall of the through hole of the rotating square plate 51, a rubber track 53 is fixedly connected to the side wall of the linkage mechanism 2, and one end of the vortex spring 52 away from the rotating square plate 51 is fixedly connected to the outer wall of the mounting block 22.

[0037] The adjusting assembly 5 also includes an L-shaped rod 54 fixedly connected to the side wall of the rubber track 53, and the end of the L-shaped rod 54 away from the rubber track 53 is rotatably connected to the top of the rotating square plate 51, and the end of the pulling spring 43 away from the fixing ring 44 is fixedly connected to the bottom of the fixing frame 41. Taking advantage of the regular swinging characteristics of the above fixing frame 41, a rubber track 53 is arranged inside the equipment, wherein, when the equipment is running, the rotating square plate 51 is affected by the release of mechanical power by the vortex spring 52, and the vortex spring 52 will drive the rotating square plate 51 to rotate downward, forcing the outer wall of the ball 55 to be in a close contact state with the outer wall of the cylindrical main furnace chamber, and the rotating square plate 51 forces the two ends of the rubber track 53 to bend downward through the L-shaped rod 54, so that the downward bending angle of the rubber track 53 The curvature is equal to the outer wall of the cylindrical main furnace chamber. When the fixing frame 41 swings, the fixing frame 41 drives the sliding rod 42 to move along the inner wall of the deformed rubber track 53. At this time, the top of the fixing ring 44 and the top of the rubber track 53 are in a sliding state. When the fixing ring 44 slides to the lower position on both sides of the rubber track 53, the pulling spring 43 will drive the fixing ring 44, the sliding rod 42 and the welding machine 45 to move downward synchronously. When the fixing ring 44 slides to the highest point in the center of the rubber track 53, the fixing ring 44 will drive the welding machine 45 to move upward synchronously. Through the application of the above components, the distance between the welding machine 45 and the outer wall of the cylindrical main furnace chamber is effectively controlled to ensure that the welding distance will not be affected by the outer wall of the cylinder, thereby improving the welding efficiency of the equipment.

[0038] The adjustment assembly 5 also includes a ball 55 rotatably connected to the bottom of the rotating square plate 51, an end of the prying rod 36 close to the fixed bracket 31 is rotatably connected to the outer wall of the rotating rod 32, and the outer wall of the sector gear 2 33 is meshedly connected to the outer wall of the sector gear 1 25.

[0039] The feeding assembly 6 includes a fixed square plate 61 fixedly connected to the side wall of the mounting block 22, a hydraulic telescopic rod 69 fixedly connected to the side wall of the fixed square plate 61, and one end of the hydraulic telescopic rod 69 away from the fixed square plate 61 is fixedly connected to the side wall of the welding machine 45.

[0040] The feeding assembly 6 also includes a hydraulic telescopic rod 62 fixedly connected to the side wall of the fixed square plate 61 . One end of the hydraulic telescopic rod 62 away from the fixed square plate 61 is fixedly connected to the extrusion groove 63 . A compression rod 64 is fixedly connected to the side wall of the extrusion groove 63 .

[0041] The feeding assembly 6 also includes a pulling spring rod 65 fixedly connected to the side wall of the fixed square plate 61, and the end of the pulling spring rod 65 away from the fixed square plate 61 is fixedly connected to a pull rod 66, and the end of the pull rod 66 away from the pulling spring rod 65 is rotatably connected to a prying rod 2 67, and the outer wall of the gear 24 is meshed and connected with the outer wall of the gear rod 15. The hydraulic telescopic rod 1 69 is compressed to drive the welding strip 610 to feed the material independently. When the welding machine 45 squeezes the hydraulic telescopic rod 1 69 to feed the material, the welding machine 45 will contact one end of the feeding welding strip 610, and the high-temperature welding machine 45 will melt the welding strip 610, so that the molten welding strip 610 sticks to the round A single welding is completed inside the gap of the cylindrical main furnace chamber. At this time, the welding machine 45 swings to the other end, and the solution inside the hydraulic telescopic rod 2 62 will return to the inside of the hydraulic telescopic rod 1 69 to reset each component. However, the pulling spring rod 65 has been in an extended state during the previous feeding. When the extrusion groove 63 begins to reset, the extrusion groove 63 is still in a taut state. The clamping force of the extrusion block 68 on the welding strip 610 still exists, and while the extrusion groove 63 is reset, the welding strip 610 is driven away from the molten metal melt. Through the application of the above-mentioned components, the molten melt is prevented from contacting and cooling with the unmelted welding strip 610, which affects the normal discharge of the subsequent welding strip 610.

[0042] The feeding assembly 6 also includes an extrusion block 68 fixedly connected to the end of the prying rod 67 away from the pull rod 66. The side wall of the prying rod 67 is rotatably connected to the inner wall of the extrusion groove 63. The inner wall of the through hole of the fixed square plate 61 is slidably connected with a welding strip 610. By utilizing the swinging characteristics of the above-mentioned welding machine 45, a hydraulic telescopic rod 69 is arranged inside the equipment. When the welding machine 45 swings left and right, the hydraulic telescopic rod 69 at one end is squeezed, and the internal space of the hydraulic telescopic rod 69 is reduced, so that the solution inside the hydraulic telescopic rod 69 passes through the fixed square plate 61 and enters the interior of the hydraulic telescopic rod 2 62, so that the hydraulic The telescopic rod 62 generates an extension force, and the hydraulic telescopic rod 62 pushes the extrusion groove 63 and the prying rod 67 to move. During this process, one end of the prying rod 67 is affected by the pulling spring rod 65 and the pull rod 66, so that the other end of the prying rod 67 is tilted upward, forcing the extrusion block 68 to contact the outer wall of the welding strip 610, and the other side of the welding strip 610 is restricted by the pressure rod 64, so that the extrusion block 68 and the pressure rod 64 form a clamping force, and as the extrusion groove 63 moves outward, the clamped welding strip 610 is sent into the processing area. Through the application of the above components, the autonomous feeding of the equipment is guaranteed.

[0043] A specific application of this embodiment is: when using the equipment, the raw materials to be welded are placed on the top of the base 1, and the accurate position is determined by the limit ring 12 to ensure that the limit plate 23 is deeply inserted into the welding groove, and the power supply of the motor 13 is turned on. At this time, the threaded rod 14 rotates, driving the threaded block 21 to move up and down, and the threaded block 21 drives the gear 24 to move up synchronously through the mounting block 22. During the upward movement, the gear 24 is affected by the toothed rod 15 to rotate, and the rotation of the gear 24 drives the rotating rod 32 to rotate through the sector gear 2 33, and the fixed bracket 31 drives the prying rod The prying rod 36 rotates, and the circular rotation of the prying rod 36 forms a regular left and right rotation through the restriction of the support frame 35. The support frame 35 drives the fixed frame 41 and the sliding round rod 42 to swing left and right regularly by rotating the long rod 34. The sliding round rod 42 drives the welding machine 45 to move up and down on the surface of the cylindrical raw material, forcing the welding machine 45 to swing to the left and right ends to increase the welding area. Through the application of the above components, the welding machine 45 presents a "Z"-shaped movement pattern during operation, thereby ensuring the welding strength of the weld of the cylindrical main furnace chamber of the single crystal furnace.

[0044] Taking advantage of the regular swinging characteristics of the above-mentioned fixing frame 41, a rubber track 53 is arranged inside the equipment. When the equipment is running, the rotating square plate 51 is affected by the mechanical power released by the vortex spring 52, and the vortex spring 52 will drive the rotating square plate 51 to rotate downward, forcing the outer wall of the ball bearing 55 to be in close contact with the outer wall of the cylindrical main furnace chamber, and the rotating square plate 51 forces the two ends of the rubber track 53 to bend downward through the L-shaped rod 54, so that the downward bending angle of the rubber track 53 is equal to the curvature of the outer wall of the cylindrical main furnace chamber. When the fixing frame 41 swings, the fixing frame 41 drives the sliding round rod 42 along the deformed The inner wall of the rubber track 53 moves, at this time, the top of the fixing ring 44 and the top of the rubber track 53 are in a sliding state, when the fixing ring 44 slides to the lower positions on both sides of the rubber track 53, the pulling spring 43 will drive the fixing ring 44, the sliding round rod 42 and the welding machine 45 to move downward synchronously, and when the fixing ring 44 slides to the highest point in the center of the rubber track 53, the fixing ring 44 will drive the welding machine 45 to move upward synchronously. Through the application of the above components, the distance between the welding machine 45 and the outer wall of the cylindrical main furnace chamber is effectively controlled, ensuring that the welding distance will not be affected by the outer wall of the cylinder, thereby improving the welding efficiency of the equipment.

[0045] Taking advantage of the swinging characteristics of the welding machine 45, a hydraulic telescopic rod 69 is provided inside the equipment. When the welding machine 45 swings left and right, the hydraulic telescopic rod 69 at one end is squeezed, and the internal space of the hydraulic telescopic rod 69 is reduced, so that the solution inside the hydraulic telescopic rod 69 enters the hydraulic telescopic rod 2 62 through the fixed square plate 61, so that the hydraulic telescopic rod 2 62 generates an extension force, and the hydraulic telescopic rod 2 62 pushes the extrusion groove 63 and the prying rod 2 67 to move. In this process, one end of the prying rod 2 67 is affected by the pulling spring rod 65 and the pull rod 66, so that the other end of the prying rod 2 67 is tilted upward, forcing the extrusion block 68 to contact the outer wall of the welding strip 610, and the other side of the welding strip 610 is restricted by the pressure rod 64, so that the extrusion block 68 and the pressure rod 64 form a clamping force, and as the extrusion groove 63 moves outward, the clamped welding strip 610 is sent into the processing area. Through the application of the above components, the autonomous feeding of the equipment is guaranteed. The rod 69 is under pressure, which drives the welding strip 610 to feed independently. When the welding machine 45 squeezes the hydraulic telescopic rod 69 to feed, the welding machine 45 will contact one end of the fed welding strip 610, and the high-temperature welding machine 45 will melt the welding strip 610, so that the molten welding strip 610 sticks to the gap inside the cylindrical main furnace chamber to complete a single welding. At this time, the welding machine 45 swings to the other end, and the internal solution of the hydraulic telescopic rod 62 will return to the inside of the hydraulic telescopic rod 69 to reset each component. However, the pulling spring rod 65 has been in an extended state during the previous feeding. When the extrusion groove 63 begins to reset, the extrusion groove 63 is still in a tight state. The clamping force of the extrusion block 68 on the welding strip 610 still exists, and when the extrusion groove 63 resets, the welding strip 610 is driven away from the molten metal melt. Through the application of the above components, the molten melt is prevented from contacting and cooling with the unmelted welding strip 610, which affects the normal discharge of the subsequent welding strip 610.
